A Suncorp spokesman said the insurer would employ construction giant Lendlease as a managing contractor to guide their response, with an emphasis on sourcing local workers.

But the sheer magnitude of the damage would mean there would be a mix of local and out-of-town workers used.

"In the first instance we always try to use local tradies because they are the people who know the types of buildings, they've worked on them before, but they can only do so much," the Suncorp spokesman said.

"Ironically, sometimes it can be a boost to the economy, because tradespeople get very busy."
